As we can see from the massive search for water on Mars, water is necessary for life to exist. Without water, there cannot be life as we know it. When food is dried, the water in it is removed. This makes it impossible for bacteria, yeast and molds - the living things that make food 'spoil' - to survive and multiply. Drying food is probably the first way that humankind started preserving food. We began by using grains like wheat that dried naturally before being harvested and progressed to the wonderful dried fruits, beans, vegetables, meats and fish that we now enjoy.
